0700200064 - ESAB M6 Contact Tip 0.030 (0.8mm) - 25mm Length - Pack of 10

Technical Overview of ESAB M6 Contact Tips

The ESAB 0700200064 is a high-performance M6 contact tip designed for precision MIG/MAG welding applications. Engineered to strict tolerances, this consumable is critical for maintaining consistent electrical conductivity between the power source and the welding wire. The tip features a standard M6 thread pitch, ensuring compatibility with a broad spectrum of gas diffusers and swan necks, particularly within the ESAB MXL torch series (including MXL 180, 200, 270, and 340 models). With a total length of 25mm, it sits at the optimal depth within the gas nozzle to ensure proper shielding gas coverage while maintaining the necessary stick-out for short-circuit and spray transfer modes.

Manufactured from high-grade copper alloy, this contact tip offers superior thermal and electrical conductivity. In MIG welding, the contact tip is the final point of current transfer to the electrode; therefore, material purity and bore concentricity are paramount. This specific tip is drilled to accommodate 0.030-inch (0.8mm) solid or flux-cored wires. The bore tolerance is calculated to allow for thermal expansion of the tip during high-amperage welding without seizing the wire, while simultaneously remaining tight enough to prevent micro-arcing inside the tip, which can lead to premature failure and erratic arc characteristics.

Industrial MRO procurement managers should note that regular replacement of contact tips is essential for maintaining weld quality standards. As the bore wears into an oval shape due to wire friction and heat, the electrical contact point becomes inconsistent, leading to voltage fluctuations and poor bead profile. This 10-pack configuration (SKU 0700200064) is designed for high-volume production environments where minimizing downtime is critical. By maintaining a stock of these OEM-quality consumables, facilities can ensure their welding operations remain efficient and compliant with welding procedure specifications (WPS) requiring 0.030" wire setups.
